Michael Plit 3021034 Isolation of a Urea Degrading Bacteria Introduction Urea was the first organic chemical to be synthetically produced^1,^ previously it was thought that only living creatures could produce organic compounds Urea is naturally produced by the kidneys as waste from the degradation of amino acids. It is because of this that urea is commonly found in soils and is a useful nutrient source for bacteria that are able to utilise it, such as, Helicobacter pylori, Klebsiella pneumonia, all species of Proteus and Micrococcus luteus. These bacteria degrade urea in a reaction catalysed by the urease enzyme, CO(NH[2])[2 ]+ H[2]O ąCO[2] + 2NH[3.] this process benefits the bacteria in several ways. The bacteria use the ammonia that is produced for respiration, the products also raise the pH of the environment. This promotes the growth of many urea degrading bacteria and inhibits competition from many other bacterial species. M. luteus is...
